To all wtom t may Concern:

e it known that I, FRANZ A. FULLER, a citizen of. the: United States,residing at Newark, in thecounty of Essex and Stateof' ew Jersey, haveinvented certainnew and usefulv Improvements in which thev following-isaspecification', refeikA encebeing had therein to thekaccompanyingdrawings, which form a part thereof.

My invention relates to bag fasteners and more particularly to a typethereof applicable to` bag frames having pivotally` con'- nected framemembers and'embodying therein a lift latch adapted to lock said framemembers when closed.

In bag frames of the character above referred to, two hingedframemembersformed of'channeled metal stock are used, and the bag bodyis secured. to the frame by having the edges thereofinserted in thechan-l nel of said members. These edges maybe held in the frame membersin any desired manner or by any desired or Well known means.

The channel of the frame members being ordinarily narrow and relativelydeep, great diiiiculty has been heretofore encountered in mounting thelift latch and its controlling spring in relation to the frame membercarrying the same. Furthermore, the ordinary construction of this liftlatch mechanism has been such as to interfere withthe conllection of thebag body to the frame meniers.

A bag fastener made in accordance with my invention is so constructedthat its attachment to the frame members may be accomplished withoutobstructing the channel in either of the body members. By thus keepingthese channels free of obstruction, the frame members may be morereadily covered, and a proper, substantially uniform clearance for theinsertion of the edges of the bag body at all points of the framemembers, is secured.

The controlling spring for the lift latch member is located eXteriorlyof the frame member, being situated within and concealed by, a box-likesupport mounted upon the frame member; and structed that the assemblingof the support in relation to the frame member will the requisitetension in the spring. This. spring when in tension will be subjected toa torsional stress having a normal tendency Bag-Fasteners; of?

thereof;

The construction of the bag fastener is such as to permit the convenientassembling of the various parts a minimum of operations, nism maybelassembled in manner to preserve the artistic lines` of the frame. Y

The invention consists primarily in a bag fastener embodyingtherein aframe consist.` ing of hinged frame members, a boxe-like support havinganv openingin the top lherev of, a lift member or knob provided.

andi this mechaof which is projected downwardly and across said supportwhereby itis adapted, when the support is mounted upon said framemember, to'engage the top of said. frame member ber; and in such othernovel features of construction and combination of parts as arehereinafter set forth and described and more particularly pointed out inthe appended.

Referring' to the drawings:

Like letters refer to like parts throughoutthe several views.

In the embodimentof my invention shown ring box-like entering theremtor,with the fran le inV with a project through .said oj'ieningclaimV heretoCIK in the drawings, the frame members are shown at a--Z the main bodyof said members being provided with hinge members a a?,- b b2respectively. Said hinge members are pivotally connected at c--0. In theform of the invention shown the :trame members a-b are composed ofchanneled metal stock. The faces of said members presented toward eachother when the bag is closed are substantially parallel so that thesemembers may be brought close together. ings, the members a-ZJ are shownas being substantially rectangular in cross-section, thus presenting aflat top. The bag fastener shown in the drawings is especially adaptedfor frame members of this coniiguration, although as it Ywillhereinafter appear, the coniguration of the frames is immaterial so longas a suitable bearing surface is afforded adjacent the lift member orknob for the purpose of engaging and tensioning the spring.

In conjunction with the frame member a, I provide a box-like support CZhaving a substantially flat top, and pendant sides @ZL-Z2 adapted tohave a sliding fit over the said frame member. The top of said supportis provided with lugs e adapted to pass through openings in the framemember a and be upset within said frame. The sides d Z2 are providedrespectively with lugs f-f adapted to foldV over and be clenched uponthe lower edges ot' the said frame member. The top'of the support Z ispierced at g to provide an opening through which the lug of the liftmember or knob is adapted to pass so as to be presented within saidsupport. The opposite ends of the top of the support (Z are drawndownwardly slightly to act as stops for the purpose of providingclearance between the top of said support and the top of the framemember a for the free movement of the lug of the lift member or knob.

The lift member or knob Zz, is of the usual construction and is providedwith the usual pendant rim 7b adapted t0 cooperate with a nose or catchupon the other frame inember b. Pendant from the member or knob l1, is alug 'i adapted to have operatively connected therewith the controllingspring for said member or knob. This lug ordinarily is provided with aspring socket Vextending longitudinally therethrough which socket isangular so as to afford a proper seat for an angular portion of aspring.

Carried within, and concealed by, the support (Z is the liftmember orknob controlling spring consisting of a looped spring one arm y' or'which is angularly formed, as at j', to have a sliding fit with thesocket in the lug c', and the other arm Zt' of which extends paralleltherewith and has its end 7c" Vturned at an angle thereto so as to beprojected downwardly and inwardly of said support to a In the draw-Vvarious lugs point below the lug i. The end Ze projects beyond the endy" so that when said spring is assembled in relation to the lift memberor knob, it will be at one side of the lug z'. The length ot' the turnedend 7c is preterably such as not to exceed the width of the top of thesupport (Z.

I provide the frame member b with a similarly constructed, box-likemember Z having riveted thereto a nose or catch member m and providedwith a loop fn, Vcarrying pull o. The support Z is attached to the framemember b by means of lugs in the same manner as the-support eZ. Y

l/Vhen the lift member or knob h has been assembled in the boX-likesupport Z by the insertion of the lug /Z thereof through'the opening inthe said support, the angular end y" of the spring j-cis slipped Vintothe socket in said lug; thus bringing the turned end 7c beyond said lugso positioning it that it is presented downwardly and inwardly of thesaid support. The sides 6Z-(Z2 of the support are then slipped over theframe anY and the lugs e inserted through the openings in the top of thetrame a. As the support Z is forced to place, the spring end Za engagesthe top of the frame. The subsequent movement of the support impartssuch movement to said end 7c as to upon the entire arm 7c with aresultant torsional and direct stress upon the arm j.;

These stresses will have the effect or' normally holding the member orknob 7L downwardly.

By arms, to be operatively connected with the litt latch lug vl and theend of the other arm being turned at an angle so as Vtoengagea suitablebearing surface on the topY of the :trame member, the mounting ofthesupport for the lift knob upon the Jframe member will impart a rotativemovement to the spring arm having its end so turned with a using alooped spring having parallel resultant slight torsional Vand directtension of the other arm. Y

When it is desired to release the latch,

Vthe i develop torsional stressesV the free end of one arm being adaptedside pressure upon said member or knob will raise it suiiicientlyagainst the tension of the spring j-lc, the length of the spring armjbeing sufficiently great to compensate for the side sway by reason oftheeccentricity of the lug z'.

It will be observed that all of the operative parts of the vlatchmechanism are sup ported within box-like members, the supportsni` and Z,including the pull. In the assembling of the device, the onlyobstructions within the trame members will be the used Jfor attachingthese supports which will be so clenched as to be substantially flushwith the walls of the frame members. It will also be observed` that itis merely necessary to slide the end The tensioning of the springresults solely from the assembling of the box-like support with theframe member. When' the spring so disarranged `as to prevent its actingupon the lift member or knob to normally close same.

It is not my intention to limit the invention to the precise details ofconstruction shown in the drawings, it being apparent that such may bevaried Without departing from the spirit and scope of the invention.
